What's the difference between a v..and...t?

terrariums: plants only
vivariums: plants and animals

I would suggest not placing carnivorous plants in terrariums as mold is a big problem in low air flow, low light conditions. Terrariums reduce the light that these light greedy plants can get. Terrariums also increase the incidence of root rot in many plants due to the problem of no drainage.

The lizards and amphibians would possibly get captured and killed by some of the plants and some of the plants might look tasty to an iguana. The idea sounds neat, but the end might be disaster. I would not mix them unless I were running an experiment on what survives.

I wasn't planning on putting CP's and critters together. I was just going to use other types of plants....suitable for a terrarium.
